How do I swap fluorescent tubes for LEDs?

You can replace fluorescent tubes with LED tubes, but the process depends on your fixture type and may require rewiring for safety and optimal performance.

There are three main approaches to converting fluorescent fixtures to LED, each with different complexity levels and safety considerations.

Direct replacement LED tubes are the simplest option - these work with your existing fluorescent ballast and can be installed by simply removing the old tubes and inserting the LED versions. However, this method is less efficient since you're still powering an unnecessary ballast, and if the ballast fails, you'll need repairs anyway.

Ballast bypass LED tubes offer better performance and longevity by eliminating the ballast entirely. This requires rewiring the fixture to send power directly to the LED tube sockets. The ballast is disconnected and power is wired straight from the electrical supply to specific pins on the lamp holders. This modification requires electrical knowledge and should be done by a licensed electrician in New Brunswick, as it involves working with live circuits and modifying the fixture's wiring.

Retrofit LED fixtures involve replacing the entire fluorescent fixture with a new LED unit. This provides the best light quality, efficiency, and appearance, but requires the most work.

Safety and Code Considerations in New Brunswick

Under TSANB regulations, modifying fixture wiring (ballast bypass) constitutes electrical work that requires proper licensing. While homeowners can replace bulbs and tubes in existing fixtures, rewiring the fixture's internal connections should be done by a licensed electrician to ensure code compliance and safety.

The Canadian Electrical Code as adopted in New Brunswick requires that any modifications to electrical fixtures maintain proper grounding and don't create fire hazards. Improper ballast bypass can create arcing, overheating, or shock risks.

Recommended Approach

For a simple tube replacement in good fixtures, direct-replacement LED tubes are homeowner-friendly. Turn off the circuit breaker, remove the old fluorescent tubes, and install the LED tubes following the manufacturer's directions. Ensure the LED tubes are compatible with your ballast type (T8, T12, etc.).

For ballast bypass or fixture replacement, contact a licensed electrician. This ensures the work meets TSANB requirements and your home insurance remains valid. Many New Brunswick electricians can retrofit multiple fixtures efficiently, often making the cost worthwhile compared to the safety risks of DIY electrical modifications.
